.MACHINE FOB POLISHING MARBLE.

Specification of Letters Patent No. 3,937, dated V.Il/[arch 12, 1845.

To all whom l? may concern;

Be it known that I, J Aco ZEIGLER, of the city of Philadelphia and State of Pennsylvania, Ahave invented a new and useful Machine for the Purpose of Polishing Flat Plates or Tables of Marble and other Articles; and I do 'hereby declare thatl the following is a full and exact description thereof. y ,v

The marble or other substance after it has been ground flat, and prepared for the I polisher by means "of the fine grained stones usually employed for 'that purpose, is tovbe laid on a fiat table with thatside upward which is to receive the polish. The table is then moved into such position as Will bring the article directly under the polisher. The polisher consists of 'a flat plate or tablet which is suspended above the table, and has its lower, or face side covered with cloth or other material fitted to receive the putty, or other polishing Substance. The polisher` is to be raised or lovvered at pleasure, and is to receive a curvilinear reciprocating motion, in a horizontal-p@ by means of two crank pins attached to revolving Wheels, Which are driven byv suitablgearing.

In the accompanying drawing A, A, is a bed, or table, upon which the marble to be polished is to be placed; this bed is made to slide in and out upon grooved guides, or

t Ways B, B, for the purpose of carrying the marble under the polisher,`or of remo-ving it therefrom; a, a, are holes through the bed to receive pegs to hold it steady. C, C, is

the reciprocating polisher, from the plates D, D, on the top of vvhich rise two pins which by passing through holes in the toothed Wheels E, E, constitute crank pins,

shown at e, e, that by the revolution of these Wheels give the desired motion to the reciprocatingpolisher. 'il-he shafts b, b, of

vWhich revolves also, at its lower end, in a box F', ailixed to the sliding head, but above this it passes through a boX I, in the cap `timber J, J, through which `box it moves up and down freely. K, is a whirl and clutch for governing the motion of the shaft.

L, L, are two levers attached at their in- Y ner ends to the lever M, M, by lin is N, N, and at their outer ends to the lifting rods O, O, that embrace the sliding head G, G. By depressing the end M, of the lever M, theV sliding head With its attachments will be raised and it may be held in any posi.- tion by a pin passing through one of the holes in the bar P. By this, and by means of the screva nuts Q, Q, on the rods O, O, the bearing of the polisher on the slab of marble may be regulated.

Having thus fully described the manner in which I construct my improved machine for polishing flat plates, or tables, of mar-y ble, c-r other substances, I do hereby declare that I do not claim as new either of the individual parts of said machine, but limit my claim to- The combination of said individual parts as above made known; said parts consisting of the reciprocating poflisher C, C, combined with the crank Wheels E, E, with the driving Wheel H, and with the sliding head, and regulating rods and levers, so as by said combination to constitute a machine substantially the same with that herein described' and represented.
